我想在我的 Ubuntu 18.04 上安装 rabbitmq。我一直在关注官方文档。但是，我的安装尚未完成，因为我卡在了这一步：sudo apt-get install rabbitmq-server -y --fix-missing因为我遇到一个错误：未满足的依赖关系。
我尝试安装 libssl，然后安装 erlang-crypto，但没有成功。我还aptitude尝试使用 安装了erlang-crypto，但它也没有安装任何软件包。
我正在运行的命令是：
sudo apt-get install -y erlang-base \
erlang-asn1 erlang-crypto erlang-eldap erlang-ftp erlang-inets \
erlang-mnesia erlang-os-mon erlang-parsetools erlang-public-key \
erlang-runtime-tools erlang-snmp erlang-ssl \
erlang-syntax-tools erlang-tftp erlang-tools erlang-xmerl
我收到一条失败消息：

该libssl包不可用，但我已成功安装libssl-dev。
我希望完整安装 RabbitMQ 并且它成功运行。
